RMI Basswitch IQ DI Bass Preamp Pedal (Discontinued)

91 out of 100. Incorporating 50+ ratings and reviews.

The RMI Basswitch IQ DI is a 2-channel preamp with expanded connectivity and tone shaping options.

It boasts of having a studio grade preamp with a Lehle LTMZ transformer especially tweaked for the lower frequencies needed by bass guitars. The preamp is complemented by a 6-band prametric EQ that can be bypassed or tweaked to your preference.

The unit’s two inputs and switchable impedance allow for using different types of instruments, from passive to active electric basses, and even piezo equipped acoustic and upright bass.

It also houses two effects loop connections, one being always on, and the other with dedicated variable mix knob and footswitch.

Finally, the pedal boasts of tour ready build with footswitches that are designed to stop your stomping weight from hitting the circuit-board.

Most reviews hail this preamp as a great piece of gear, if not the best preamp ever. One user described the sound as Hi-Fi quality, a sentiment that is shared by many experts and users who are blown away by the sound quality. Professional bassists dig its versatility both in terms of connectivity and sound shaping. The unit’s neat and aesthetic appeal are also complemented.


There aren’t many complaints other than it’s above average price tag.

  1. I sold this preamp and tried many different boutique brands. I came back to it. It really is the best around! Love it and, I won’t sell it again!
